about us


In 1979, ASM Industries Inc. was established by Alfred Stanley Marlow with the development of the pump we use today. Over the next three years, ASM Industries operated as one entity. Then, in 1982, Service Filtration Corporation owner Jack Berg purchased ASM Industries and divided the functions of the company into two separate sister organizations: Polymar and Pacer Pumps. This division opened the doors for both business units to become their own profit entity, thus promoting growth. It was at this point, Polymar moved from an entirely captive molding provider for the Pacer Pump to becoming a custom molder.

Early on, the pumps were molded from PBT polyester. Polymar worked closely with DuPont on the development of Rynite®, a PET polyester. The Pacer Pump was converted to this material. It was this expertise in drying and molding PET polyester resin that launched our business.

Today, Polymar services many markets, such as tier two automotive, medical, construction, electrical and fluid transfer, supplying customers with such diverse products as gears, cams, medical disposables, electronic enclosures, interconnection devices, coil bobbins, optical components, under-the-hood electrical motors, and pump housings.


Polymar is committed to providing value to its customers through offering the highest quality custom plastic injection molding. Building on over 30 years of business, Polymar combines experienced staff, quality materials, and tooling designs with a strong attention to detail to produce only the best products for their customers. By focusing on, and exceeding expectations, Polymar is able to manufacture the product you need within the time you need it.
